:,0 Fig. 2 is a side eevational view of the same; Referring now particularly to Figs. 3 to 6 in- 50 Fig. 3 is an enlarged, pan view of the aforeclusive of the drawings, the numeral 24 desigsaid illustrative embcdiment of the present invennates a bell-crank lever pivotally mounted upon tion having the cover plate removed to show the a shaft 25, the lever being provided with an inner construction, the device being shownv in its arm 26 which is bifurcated at the outer end thereinitial condition prior to dialing; of so as to carry a spring-pressed dog 21 adapted 55 to be engaged, in a manner to be hereinafter more fully explained, by a lug 28, affixed to the dial I5 of the telephone by straddling the rst dial opening 29. It is preferred that the lug 28 be so affixed to the dial I5 that it cannot be removed without the use of a special wrench; for, if this is not the case, the telephone may be used by removing the lug 2B and therefore not counting the calls made.

The bell-crank lever 24 is provided with another arm 30, the end of which is likewise bifurcated so as to carry a spring-pressed pawl 3l normally resting against a stop 32 which limits the downward movement thereof.

Also pivotally mounted upon the shaft 25, adjacent the lever 24, is a toothed sector 33 provided with a pin 34 extending into the path of the arm 26 of the lever 24, in contact with the lower edge of the said arm, the sector being further provided with another pin 35, extending outwardly from the opposite face of the sector which carries the pin 34. Formed with the sector 33 is a collar` 36 and at the outer end of the collar, there is integrally formed, a bar 31. Immediately adjacent the bar 31 and pivotally mounted upon the shaft 25 is another bell-crank lever 38, said lever consisting of an arm 39 provided, near the outer end thereof with a pin 40 which extends outwardly from both sides of the arm 39, the extension on one side being in the path of the bar 31, in contact with the upper edge thereof. The lever 38 includes another arm @l which constitutes a catch member to set or cock the counting mechanism preparatory to recording the completed call as will hereinafter be more fully explained.

The toothed sector 33 engages a pinion l2 integrally formed with a shaft Q3 rotatably mounted in the casing i1, the end of the shaft i3 opposite the pinion l2 constituting an anchor for the inner end of a coil spring M, the other or outer end of which is xed t6 a spring housing 45. Loosely mounted upon the shaft d3 is a sleeve i6 having aixed thereto a gear l1 which carries a spring-pressed pawl it engaged with the pinion l2 in such a Way that the pinion is free to rotate in a clockwise direction Without effecting the gear l1 but adapted to constitute a link between the pinion l2 and the gear l1 so that rotation of the pinion in a counter-clockwise direction similarly rotates the gear. The gear 61 meshes vwith a pinion i9 amxed upon a shaft 5@ `which also has affixed thereon a gear 5l in `mesh with a pinion 52 alxed upon a shaft 53. 'The shaft 53 also has affixed thereon an escapement Wheel 513 controlled by a pivotally mounted escapement 55. The purpose of the gear train just described is to control the speed with which the coil spring ifi unwinds after it has been wound to an operable condition by the action of the sector 33 upon the pinion (i2.

Referring now particularly to Figs. 3, 4, and 6 62, is a half tooth, the ratchet wheel being operable, in a manner to be hereinafter described, by.means of the pawl 3i constituting part of the lever 24.

The ratchet wheel 60 is normallyurged in a counter-clockwise direction by means of a spring, not shown in the drawings. During the operation of the device, it is necessary to prevent the spring just mentioned from urging the ratchet wheel 60 to its normal, inoperative position and in order to do this, I provide a dog 63 formed on a. spring-pressed pivotally mounted bar 64, the dog 63 being normally maintained out of contact with lthe ratchet Wheel 60 in view of the fact that the arm 64 is in contact with the lower edge of the bar 31. The ratchet wheel 60 carries a pin 65 which, during the normal, inoperative position of the ratchet wheel is in contact with the underside of a. stop 66.

The pin 65 is adapted, during the course of the operation of the device, as will hereinafter be morey fully explained, to engage a depending tail 61 formed on a slide 68 mounted in a U-shaped bracket 69 carried in the casing,`one of the openings 10 of the bracket 69 being enlarged so that the slide 68 can move arcuately as well as laterally. 'I'he slide 68 is provided with a stop 1I which is normally in contact with a portion of the bracket 69, the slide being maintained in this position by means of expansion spring 12, one end of which urges against a portion of the bracket 69 and the other end of Which urges against a lug 13 struck up from the body of the slideAitself.

Pivotally mounted in the casing, above the slide 68, near the end thereof opposite the tail 61, is a spring-pressed latch 14 adapted, as will hereinafter be more fully described, to be actuated by a tripping dog 15 pivoted at 16 to a lever 11 in turn pivotally mounted in a bearing 18 formed in the casing. In order to permit the arcuate movement of the lever 11 and at the same time conserve space, I provide the latch member 1li with a notch 16 and in order to control, as will hereinafter be more fully described, the operation of the` tripping dog, 15, I provide the slide 66 with a notch 86.

At the end of the lever 11 opposite that which carries the tripping dog 15, I provide a coupling 8i by means of which the lever 11 is pivotally connected with a rod 62 extending upwardly through a tubular extension 63 of the casing l1,

- the rod 62 having anlxed to the upper end thereof a plate M adapted to overlie the hook i4, as most clearly seen in Figs. l and 2 of the drawings.

This completes the description of the aforesaid illustrative embodiment of the present invention and its operation and mode of use may be summarized as follows:

With the receiver on the hook the positions of the various elements of the present invention are seen in Figs. 3 and 4. As soon as the receiver is removed from the hook, the hook" moves upwardly to close the circuit through the telephone so as to permit a call to be made. This movement of the hook it is transmitted through the plate til, connecting rod 82, coupling 6l, and lever 11 to the tripping dog 15 so as .to move the latter into a position where its operating end will be beneath the latch member 14. With the device in this condition a call can now be made.

As the dial i5 is operated for the first time, the lug 28 cornes into contact with the dog 21 and pivots the lever 24. certain point in the course of its arcuate movement, it clears the dog 21 so as to permit the pivotally mounted lever 24 to return, by its own weight, to its normal position. On the return movement of the lug 28, said lug Will come into When the lug 28 reaches a contactwith the under edge of the dog 21 and merely pivot the same out of the Way so as to permit the lug to pass it by and be ready for the next movement of the dial I5.

The operation of the lever 24 accomplishes two things. In the rst place the pawl 3| comes into contact with the teeth of the ratchet wheel B and rotates the same the distance of one tooth. In the second place, because of the contact between the arm 26 of the lever 24 and the pin 34, the toothed sector 33 is pivoted upon the shaft 25 s0 as to rotate the pinion 42 and so store up energy in the spring 44. When the sector 33 pi-vots under the urgence of the arm 26, the bar 31 is likewise pivoted so as to release the bar 64 and permit the dog 63 toengage the ratchet wheel 60 and prevent the return movement thereof. At the same time the bar 31, through the pin 40, raises the arm 39 so as to pivot the bell-crank lever 38 and thus move the,

other arm 4I of the said bell-crank lever into such a position that it is engaged by the latch member 14. Until the latch member is tripped, as will hereinafter be described, the lever 38 is maintained in its locked position. The' upward movement of the arm 39 also raises the counter arm 58 so as to set or cock the counting mechanism 56 to register a call upon the release of the arm 58. The position of the parts in their so-called cocked position will be more fully understood by reference to Fig. 6 of the drawings. It is to be understood that the various movements and conditions just described are al1` brought about upon the rst movement of the dial I of y the telephone.

'I'he next movement of the dial will, through the lever 24, operate the ratchet wheel 60 so as to move the same the distance of another tooth and, assuming that it takes seven dialings to make a call, as is the case in New York City, the ratchet wheel SII/will be rotated the distance of one tooth each time that the dial is operated until the seven dialings have been made. If any further dialings are made, the pawl'3l will encounter the half tooth 62 as a result of which the ratchet wheel 60 will not be further rotated.

'When the ratchet Wheel 60 is rotated the distance of one tooth for the seventh time, the pin 65 will come into contact with the tail 61 of the slide 68 and move the slide 68 to the right, in

Fig. 3 or 6, against the action of the spring 12.,

This movement of the slide 68 will take the notch 80 out of register with the tripping dog 15, it being understood that when the mechanism is not in use, this notch is in register with the dog, so that upon the happening of the following, the dog will be in condition to trip the latch member 14.

I have arranged the spring 44 and the train of gears which controls the unwinding thereof in such a manner that it takes seconds for the sector 33 to return to its normal position after the seventh dialing has been made. The purpose of this will be explained.

As the spring 44 unwinds, the pinion 42 drives the train 41, 49, 50, 52, 54, and 55, the train controlling, as has been stated, the speed with which the spring unwinds. The counter-clockwise movement of the pinion 42 returns the sector 33 to its normal position shown in Fig. 3 of the drawings. As the sector reaches the end of its return movement the pin 35 carried thereby comes into contact with the underside of the slide 68, and lifts the same arcuately upwardly so as to transmit an upward movement to thev tripping dog, 15. The dog in turnv lifts the latch member 14 to release the arm 4I of the lever 38 and the releasing of this lever permits the vcounter arm 58 to return to its normal, downward position, thus operating the counting mechanism56 to record the call. Upon the return of lthe sector 33 to its normal, inoperative position, the dog 63 is moved out of engagement with the ratchet wheel 60 and the latter returns to its normal position and the return of this member to its normal position permits the slide 68 to likewise return to its normal position.

This completes the description of the normal operation of the aforesaid illustrative embodiment of the present invention in the course of making a conventional call. It is to be noted that in order that the counter mechanism operate to register a call, there are two conditions that the `device must be in or else the call will not be counted. In the rst place, the receiver must be off the hook so as to move the tripping dog 15 to its operative position' beneath the latch member 1'4. -If the dial is operated while the receiver is on the hook, no call can be counted for the reason that, even though the counter arm 58 is cocked to a position permitting the operation of the counter mechanism 56, any upward movement of the tripping dog 15 will not be .transmitted to the latch member 14 and so the counter arm 58 -will not be released. In addition, unless the notch 80 is out of register with the tripping dog 15, no call can be counted for the reason that any upward movement of the slide 68 will not be transmitted to the tripping dog 15 unless the dog and notch are out of register. In order that the dog and notch be out of register, it is necessary that the dial be operated seven times, for without this, the pin 65 will not engage the tail 61 to move the slide 68.

Because of these fool-proof features, dialing when the receiver is on the' hook will not bring about registering of a call even though the dial be operated seven times. Also, though the receiver =be oil' the hool-r, a call will not be counted if the dial has notfbeen operated seven times, in other Words, less than the number of times necessary to make a call. Finally, because of the timing feature above described, even though the receiver has been oil' the hook and the dial has been operated seven times, a call will not be registered if the receiver is returnd to the "hook before the completion of the return movement of the sector 33 which, as above stated, takes place 30 seconds after the seventh dialing has been made. This will enable lthe user to hang up if a busy signal is obtained. Obviously if this amount of time is deemed insufcient, minor adjustment of the device can be made so as to change the time to any particular amount desired.
